FrontierStack AI
FrontierStack includes free use of FrontierStack's AI servers for now, so you can run the AI Harness without supplying a provider key. The default Qwen3 engine runs through Enfour's AI Cloud. Availability, limits and pricing may change in the future.
- Zero retention is required and attested on every response
- Provider credentials and upstream endpoints remain on Enfour servers
- Prompts are deterministically redacted before leaving your Mac
- Strict Harness guard-rails, tool restrictions and action approvals remain enabled
FrontierStack AI is optional. You can instead bring your own key from a major AI platform or run a local model with Ollama, LM Studio, Apple Intelligence, or another compatible local engine.
